TOYLZZ whom t may concern:

Be it known that I, HERVEY N. ANDREWS,

y a citizen of the United States, residing at Greenfield, in the county of Hancock and -State of Indiana, have invented certain new and useful Improvements in Adjustable Beds, of which .the following is a specification.

This invention relates to improvements in adjustable beds, and has special reference to the adjustment tress-holding portions, cent to the head of the into position oblique to the major lower portion of the bed-bottom, as is often desirable with invalids when it is desiredv to permit them to assume a sitting or partially-sitting bed may be elevated posture.

lI accomplish the objects of the invention by the mechanism illustrated in the accom-panying drawings, kin which- .Figure l 1s a longitudinal vertical sectlon :of my improved bed, showing the bottom in its horizontal position; and Fig. 2 is a like longitudinal vertical section showing the bottom adjusted to an oblique position for the potion thereof adjacent to the head of the be Like characters of reference indicatelike parts throughout both views.-

While `I have here shown a wooden bedstead, it is obvious that my invention equally applicable to iron and otherl metaly beds, and I therefore do not desire to limit my invention to the particular kind of bedsteads shown in the drawings.

Referring to the drawings, 1 represents the head, 2 the foot, and 3 the side rail connecting said head and foot. Secured to theinner side of the side rail adjacent to the foot 2 is the block 4, having an upper oblique edge which slopes downwardly from the topv of the lrail 3. This edge has a longitudinal groove to" receive a tongue 5 on the end of the board 6. This tongue isshown in dottedlines in the drawings. The board 6 extends approxi-- mately two-thirds of the length of the side rail 3, and its end having the tongue 5 is oblique to t the obliqueend of the block 4. Secured by means of the hinge 7 to the lower corner of the opposite end o f the board 6 is the bar 8, which is pivotally secured at 9 to the side rail 3. The end of the bar Sadjacent to the board 6 is made tapering, as shown, so as not tointerferewith the lowering of the board 6 bythe contact of the barl with ofthe bed-bottoms or mat- 4lo whereby parts adja- 4ment of the board 6 would be attended by a swinging upward movement of theouter end of the bar v8. The movement of the bar 8 below the horizontal line of the bottom of board 6 is prevented by the block 10, which is fastened to the lower edge of the side rail 3' for the purpose of forming a stop to arrest said Connected by means of the hinge 11 to the upper inner corner of the boards6 is the bar 12.v The bar 12 has a bearing uponthe roller 13, and the roller 13 is mounted upon the adjacent edge of the bar 8.

By the above construction it will he observed that a lowering of the board 6-will cause the bar 8 to swing in an upward direction, and thereupon the bar 12 will be forced by thebar 8 into a corresponding oblique upward position, such as is clearly illustrated in Fig. 2. Anyl desired angular position of the oblique parts with relation tothe board 6 maybe obtained within the' range of adjustment of the bed, and in order to maintain a given adjustment I provide the longitudinally-slotted bar 14, which is pivotally connected at one of its ends to the ears 15, fastened to the under side 'of the bar l8.. A bolt 16, supported by the side rail 3, is located between the ears l5 and hinge 7 (speaking now of the horizontal position of the bed-bottom) and this bolt passes through the longitudinal slot in the bar 14 and terminates with a screw-threaded end, on4

which a wing-nut is screwed, .as shown in the drawings. By screwing the nut in against the slotted bar the latter-can be locked, and thereby a given position of the adjustable bar 8 will be held. The ears` 15 and bolt 16 when placed Yas above described and as shown in the drawings/will cause the bar 14 to fold upautomatic'ally against the under side of bar 8 when the bed-bottom is in its horizontal adjustment.

I have here described the construction and operation of parts as applied to one of the bedrail's, and as the parts are merely duplicated for the other bed-rail it is obvious that the description given for one side, as above, will suffice for both.

Any suitable mattress will be attached to the-board 6 and bar 12. vIn the drawings I have shown a wire mattress 18, but do not desire to be limited to thatkind of a mattress.

Having thus fully described my invention,

what I claim as new, and wish to secure by Letters Patent of the United States, is.-

1. In a bed, the bed-rails, blocks secured to the inner side of said bed-rails at the foot, said blocks having upper edges which slope downwardly toward the head of the bed, horizontal vertically-movable boards each having oblique ends resting upon the oblique edge of its respective block, bars for each bed-rail pivoted to its rail and hinged at its end to the lower corner of its adjacent board, a second bar hinged to the upper corner of each board and bearing upon the underlying pivotcd bar.

2. In a bed, the bed-rails, blocks secured to the inner side of said bed-rails at the foot, Said blocks having upper edges which slope downwardly toward the head of the bed, hori- Zontal vertically-movable boards each having oblique ends resting upon the oblique edge of its respective block, bars for each bed-rail pivoted to its rail and hinged at its end to the lower corner of its adjacent board, a second bar hinged to the upper corner of each board and bearing upon the underlying pivoted bar, and means to hold a given adjustment of the above parts.

3. In a bed, the bed-rails, a bar pivoted to each bed-rail, a board hinged to the end of said bar having vertical adjustments against a bed-rail, means to support and guide the opposite end of the board, a second bar for each rail hinged to the end of said board and bearing upon the pivotcd bar, a longitudinally-slotted bar pivotally secured at one end to the pivotcd bar, a bolt passing through the slotted bar, and a nut on said bolt.

4. In a hed, the bed-rails, a bar pivotcd to each bed-rail, a roller on each of said bars, a board hinged to the end of said bar and having vertical adjustment against a bed-rail, means to support and guide the opposite end of the board, a second bar for each rail hinged to the end of said board and bearing upon the roller on the pivoted bar, a longitudinallyslotted bar pivotally secured at one end to the pivoted bar, a bolt passing through the slotted bar, and a nut on said bolt said bolt being located between the pivotal connection of the slotted bar and the hinge between the pivotcd bar and board.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 15th day of April, A. D. 1905.
